How can I replace an existing image on a winforms ImageList?

Question

How can I replace an existing image on a winforms ImageList?

I tried this:

this.CoolPics.Images [ 2 ] = // new image
this.ListViewControl.SmallImageList = this.CoolPics;

However the new image is not rescaled the way the others are, when I used the this.CoolPics.Images.Add method.

What am I doing wrong?

Answer 1

after your code try

listView1.Refresh();

Answer 2

I have run into this before and if I remember right the assignment operator had this behavior but the Imagelist.Images.Add(myImage) did the right thing.

Try changing your code to do the .Add(myImage) and see if that doesn't look better.
